◆ lfo_wave_t

Defines the wave form type used by an LFO (gig format extension).

This is a gig format extension. The original Gigasampler/GigaStudio software always used a sine (sinus) wave form for all its 3 LFOs, so this was not configurable in the original gig format. Accordingly setting any other wave form than sine (sinus) will be ignored by the original Gigasampler/GigaStudio software.

See also

Enumerator
lfo_wave_sine 

Sine (sinus) wave form (this is the default wave form).

dimension value between 0-127

split_type_bit 

dimension values are already the sought bit number

Definition at line 354 of file gig.h.

◆ sust_rel_trg_t

Defines behaviour of release triggered sample(s) on sustain pedal up event.

This option defines whether a sustain pedal up event (CC#64) would cause release triggered samples to be played (if any).

Note: This option is an extension to the original gig file format, so this option is not available with the original Gigasampler/GigaStudio software! Currently only LinuxSampler and gigedit support this option!

By default (which equals the original Gigasampler/GigaStudio behaviour) no release triggered samples are played if the sustain pedal is released. So usually in the gig format release triggered samples are only played on MIDI note-off events.

Definition at line 482 of file gig.h.

◆ vcf_type_t

Audio filter types.

The first 5 filter types are the ones which exist in GigaStudio, and which are very accurately modeled on LinuxSampler side such that they would sound with LinuxSampler exactly as with GigaStudio.

The other filter types listed here are extensions to the gig format and are LinuxSampler specific filter type implementations. Note that none of these are duplicates of the GigaStudio filter types. For instance vcf_type_lowpass (GigaStudio) and vcf_type_lowpass_2p (LinuxSampler) are both lowpass filters with 2 poles, however they do sound differently.
